So this afternoon I realized it is not blowing out. Its taking in at the intake site, but not blowing anything out of the vents. Our house is only 5-6 years old. We have lived here maybe 4. We've never had any problems with the AC, so never done anything to it. Outside coils look fine. Have not been upstairs. Breaker is fine. Any ideas?

Now why are you so sure that the unit is pulling air? Is there a lot of ice on the condensor coil? Do you have duct work in a crawl space that an animal may have gotten to and chewed a hole in a trunk line. A little more info would be appreciated. Feel free to post pics of the unit and ducting.

I didnt see any ice at all on the coil. Right before I noticed it went out I felt it pulling air at the site of the intake. No everythings in the attic. I dont think anyones been up there at all for months. I just went up there, and i dont really know what to look for. Its a Trane . I can post pics what else would be helpful?

Sounds like you have a split unit with a compressor outside and an air handler in the attic. If your compressor is running, your thermostat is correctly calling for cool, so that's probably not the issue. My guess is there's a dedicated breaker for your air handler that has tripped, disabling it. Note that there may be two breakers just for the air handler (and a third for the compressor)-- mine has one in the panel and an extra one in the attic, mainly meant as a maintenance shutoff I believe.

You might also check to see if the overflow pan below the air handler has water-- in so, there should be a sensor that's detecting this and disabling operation. In my case there are two sensors, a flow sensor on the overflow valve and a float sensor on the bottom on the pan. I know this because one recently went bad and disabled my a/c too. I had to pull them out of the circuit to get things going-- got a replacement ASAP, but I was willing to risk an overflow to get some cool air!

OK, let me make sure I understand what's going on. First, a few notes. The outside unit does not have any connection to air blowing or not inside, it unit just receives the coolant, removes heat from it, and sends it to the air handler in the attic. The air handler in the attic has the fan which circulates air in your house-- it passes the air over over pipes filled with coolant (vast oversimplification) chill the air. The "fan" on the compressor outside just pulls outside air through the outside unit only-- it doesn't do anything to inside air.

OK, troubleshooting steps.

If you turn the a/c as low as it will go and leave the fan on auto, what happens on both the outside unit and the inside unit? You may need to leave it there for up to five minutes before anything happens due to built in delays. If the outside unit fan comes on, that means the compressor has power and is receiving the cool signal correctly. If not, it doesn't matter what the inside unit is doing, and you probably have a power problem on the compressor or a bad thermostat (or control wiring). Depending on how the wiring is set up, you might also have a bad sensor as I mentioned in my first post, but that's a tricky one to diagnose w/o a multimeter.

Next step, if the compressor outside (fan) turns on but the air handler in the attic isn't blowing at all, leave the thermostat set to max cool and turn the fan to "ON". This will circulate air no matter what the temp. If no air still blows, there's probably a power problem to the air circulator.

If air blows but it never gets cool, there's a problem in your coolant system and you'll definitely need a HVAC tech to resolve. I'm still thinking there's an extra breaker somewhere that's tripped. I'd go up in the attic and see if you can find one. Take a look at your overflow pan too while you're up there to make sure it's not full. If your condensation line is clogged, that can lead to an overflow which then leads to a shutdown.
